5.3. Common faults analysis and treatment
No
Fault
phenomenon
Reason analysis
Solution
1
The
indicator
does
not
respond after the
power on
Total voltage lower than 35V
Check the total
voltage
2
No DC output
Battery data status is abnormal.
Battery gets into over-discharged
protection
Read
the
battery
information on
the monitor.
3
The DC power
supply time is too
short
Battery capacity become smaller
Storage
battery
replacement or
add
more
modules
4
The
battery
cannot be fully
charged to 100%
Charging voltage is too low
Adjust
charging
voltage
at
53.5V or 54V
5
The power cable
sparks
once
power on and
ALM light RED
Power connection short-circuit
Turn off the
battery, check
the cause of
the short circuit
6
Communication
fault
The DIP setting of the host is wrong/
the battery type of the inverter is
wrong/
Communication cable used
incorrectly/
communication cable is incorrectly
connected at the battery comm
port or the inverter comm port/
The battery firmware version is not
supporting the inverter
Check
these
possible causes
one by one
